Status and prospect of research on positioning of targets in underground coal mines
Abstract:This paper summarizes various positioning techniques developed recently years of personnel/machine in underground coal mines, such as the iBeacon underground positioning technique, UWB technique underground dynamic positioning technique, WMSNs video miner"s lamp positioning technique, TWR and SDS-TWR positioning method, asynchronous time measurement underground coal mine personnel positioning technique, multi-sensor information fusion coal mine personnel positioning Methods, GRPM coal mine personnel positioning technique, positioning of underground shearer based on SNIS/axis encoder, underground targets positioning based on improved UWB algorithm and so on. And from the effects of the conductors and obstacles in the underground roadway and its support and underground roadway, whether the clock synchronization between the base station and the mobile terminal is required or not, whether the clock synchronization between the reference stations is needed or not, and the frequency offset of the mobile terminal and the reference station clock frequency, cost of base station, cost of reference station, cost of mobile terminal and positioning accuracy are comprehensively evaluated for the advantages and shortcomings of a variety of positioning techniques. Research and development of a new combined underground precise positioning system to make that transmission signals are not affected by the underground roadway environment, no need for clock synchronization, small positioning equipment complexity, low construction cost of base stations and reference stations, high positioning accuracy, and visualization of positioning and navigation is the key link to achieve the precise position service, precise control of underground targets management and mature intelligence of coal mines.
